During the game, players can engage in battle by placing mahjong tiles on their bench onto the board. Each mahjong tile has a corresponding position and type. Different bond effects can be activated when a certain number of tiles with the same position or type are deployed. Each mahjong tile has a basic attack and an ability. The ability is cast automatically when energy is full. (Some abilities are passive and will always be in effect.
At the beginning of each turn, the tile box will be automatically refreshed once. This automatic refresh will not cost coins. Manual refreshes will cost 2 coins each time. There will be 5 tiles drawn in the tile box in the beginning. When the maximum number of tiles is at level 9 and 10, each draw will have 6 and 7 tiles respectively. You can tap to lock the tile box. Once locked, the tile box will not be automatically refreshed at the beginning of each turn.
Card Pool: In a match, all players will share a common card pool. In the beginning, all mahjong tiles are included in this card pool. When players draw tiles, they will be moved out of the card pool into the tile box. Tiles in the tile box that are not purchased and sold tiles will be returned to the card pool. All the player's tiles will be returned to the card pool upon their death. There are 5 tile qualities. The quantity of the different quality tiles in the card pool differ.
Probability: The higher the player's maximum tile level, the higher the probability of drawing high quality tiles. At the same time, the probability of drawing low quality tiles will decrease.
Board: The battlefield of the game is a board 8x8 squares large. Players play as the defender, with their tiles located in the bottom half of the board. The enemy for the turn is the attacker, with their tiles located in the top half of the board. Apart from monster turns, the player's attacker each turn is randomly chosen from the remaining surviving players. When the player is the attacker, their board will be mirrored on the other party's board, taking the horizontal middle line of the board as the central axis.
Placement: Mahjong tiles that the player purchases from the tile box will be placed on their bench. Players can drag tiles from the bench onto corresponding squares on the board. Tiles can only be placed on the bottom 4 rows of the board. During the lock phase, players cannot place or move their tiles but can sell or withdraw tiles back onto their bench. If the number of tiles on the board exceeds the maximum, the last tiles that have been placed on the board will be returned back to the bench according to the exceeded number. If the bench is full, the exceeded tiles will be sold. A maximum of 8 tiles can be kept on the bench.
Promotion (Peng): The mahjong tiles are split into 5 different qualities. When 3 of the same tile with the same quality are placed on the board together, it will trigger a promotion. 3 1-star tiles will be combined to form 1 2-star tile; 3 2-star tiles will be combined to form 1 3-star tile.
